Hi, I've tried to install Mavericks on my system, but unfortunately I don't even make it to the installation screen. Bios is set up properly and I've got an intel processor, nvidia graphics and an Asus mainboard. When booting verbose it gets stuck with the following error: USBMSC Identifier (non unique): 058F63646476 0x58f 0x6364 0x100, 2 Still waiting for root device What could that be? Does anybody know a solution? Thanks in advance! Intel Core i3-3240 @ 3,4 Ghz 8 GBs of RAM nVidia GeForce GTX 650 Asus B75M-A
